Three girls now I've had to sit down (2 of them) or text and cancel plans with them (1 girl) simply because I didn't click with them. All but one (the one I texted) I had at least held hands with. They all continued to text me (part of the reason, they were all really kind of needy), they all got upset and I feel kinda shitty about it. How do you guys reject the girls you end up not liking? How well do they take it? How do you deal with lash outs/crying/clingyness?

I basically say I'm looking for an open relationship/non exclusive, so I get why they might be pissed but still.
